Description
🔹 Product Overview
The GE IS215VCMIH2C is a VME Communications Interface (VCMI) board used in the GE Mark VI Speedtronic turbine control system. It functions as a VME bus master and provides the communication interface between the main controller, I/O boards, and the IONet control network. The H2 version provides three IONet 10Base2 Ethernet ports, supporting R, S, and T communication channels for simplex and TMR system configurations.
The board uses a 32-bit processor architecture with dual-port memory and includes an RS-232C serial interface. It also manages rack board identification and communication between VME-based control and I/O hardware.

⚙️ Application
The IS215VCMIH2C serves as a central communication interface within compatible GE Mark VI control racks. It manages VME bus communication and provides the connection between the controller and I/O boards while interfacing with the IONet system control network. In TMR configurations, its three IONet ports can support the R, S, and T communication channels.
🛠️ Installation Notes
Before replacement, verify the complete IS215VCMIH2C part number, hardware revision, Mark VI rack configuration, VME backplane compatibility, and IONet architecture. The H2 version is specifically associated with three IONet ports, so the installed communication configuration should be checked before substituting another VCMI revision.
📦 Condition
